72dpi vs. 300dpi

After a few guesses of attempting to guess what dpi stands for I’ve concluded that it is an abbreviation for Dog Pee Incidents. However, the intellectual internet has yet again taught me something new; Dpi stands for dots per inch.

What’s Dpi?

Dots per inch refers to the print on posters, banners, and several other printable objects that use dots of ink per inch to determine the quality of a printed image. In simpler terms, the higher the dpi the more detail would show in the finished printed product.

DPIs used for Printing and Web

The DPI may have to be altered depending on how the designer will exhibit his or her work. If the designer chooses to print their work, they must use a DPI of at least one hundred and fifty (typically three hundred.) It is important to have a  high dpi otherwise suffering of one’s self is guaranteed due to the poor quality If the designer chooses it to add their image on a blog it would be ideal to use a DPI of 72.  This is because it is considered the standard dpi for web images.

  Resolution also plays a great factor in images because if an image is taken in with a low resolution (like a flip phone or an old android tablet) then no matter what dpi the image is set to; it will come out in bad quality. In order to avoid that situation, designers should use only the most advanced camera for professionals, DSLR cameras. A DSLR’s resolution can go up to 50.6 megapixels for each photograph.

  Another important factor is the size of the computer’s monitor that any designer is  working on — which can alter the dpi of the image. For example, a monitor with the resolution of 1024×768 will have a dpi of 70. While in a monitor with a resolution of 1280×1024 would have a dpi of 87. This would result with a smaller image but with greater detail because of the density of pixels on the monitor or PPI (also known as Pixels per Inch.)

Later on in our multimedia class, we will have to know by prior knowledge when to use which types of DPIs which makes all of us just a little bit better.

Basic Computer Components

Without basic components, a computer will never be able to function. What does a computer need to operate? The essentials are a CPU, RAM, a hard drive, and a monitor.

CPUs

All my life I thought CPU meant Cat People Unite! Just kidding, CPU is the abbreviation for Central Processing Unit. As the name describes, the CPU receives information that translates it to actions in the computer. The clock speed is what determines the amount of commands it can process at the same time. This is measured in gigahertz (GHz.) The CPU looks like a small square that is placed in like a perfect puzzle piece on the motherboard.

RAM

RAM means Random Access Memory. Its purpose is to keep things at a short reach like clicking a separate tab instead of clicking the Google Chrome icon and searching for whatever you needed. It is basically a temporary memory that deletes when the computer turns off. RAM is measured in gigabytes and ranges from 4 to 16 GB.

Hard Drive

A hard drive is a data storage device that contains information permanently.  Information like software, downloads, pictures, documents, and several other things. Unlike RAM, the hard drive saves its information even when the computer is shut down. The hard drive has a data cable and a power cable that is connected to the motherboard. Inside this component looks much like a record player. It contains an aluminium platter, actuator arm, and a head (along with other technology.) The head, which is moves by the actuator arm caused by magnetic force, scans over the platter and reads magnetic signals in the form of zeros and ones.  The platter rotates up to 10,000 revolutions per minute! Storage is measured in gigabytes(GB) and terabytes(1,000 gigabytes.) Usually, computer contains from 500 GB to 3 TB (terabytes.) A standard size of a hard drive is 3.5 inches and for laptops it is smaller by an inch. 2.5 inches.

Monitor

The monitor is also known as the screen of the computer. This is could be connected by either HDMI, DVI or a VGA cable. This cable is connected to the motherboard to show what is going on the screen. There are various kinds of resolutions a monitor has: from the basic 800×600 to 4K resolution. Sizes also matter and can range from 17 inches to 24 inches or even bigger. Nowadays some monitors are touch screens meaning that they response to the  tap of your finger. The best part about monitors is that you can connect 2 or more to your computer and have a tab open for each monitor to achieve efficient multitasking!
